Just twigged that OL is you, Tracey! I would have put my netting up first. I did like you a couple of yrs ago, then trod on some when the dog barked beside me and gave me a fright! Most recovered eventually, but I was so mad!
I have done two batches (didn't get time to do all at once), in deep paper pots. I germinated the first batch on heated prop at end of feb, then slung them straight into cold frame. Wide open in day, then partly open at night as the wind tried to wreck the top a couple of times! They are now nearly ready to pinch out. Last batch I did last wk in cold conservatory, as no room left in prop. They are slower in showing me any shoots, but I'm sure they will soon. All going out as soon as tall enough. Thinking of taking the first lot out of the frame tomorrow, as need the space.
Incidentally, I have some spare fuchsias in the frame too, that weren't so great last year, but showed some better growth later on. I put them in the frame over winter (the better ones got mollycoddled in the GH), and although supposed to be tender ones, they are just as happy as the SP's and, caulis and young strawberries. They have thrived from neglect, so perhaps we spoil too many of our plants? I have also moved my toms into the GH this wk, and they seem to be doing fine with a propagator top on at night. (the GH is bubble-wrapped)
So, David, I am treating most of my plants meaner this yr. I think many can stand more cold than we are led to believe, provided kept dry and out of nasty cold winds.
